New barrel and tang fitting

[Cajun72]

Well I have a CVA Mountain Rifle in 50 cal with a bad barrel. Found a USA made barrel in .45 cal in the white has some surface rust but bore is excellent. So when trying to install in the tang on my stock it does not fit? Seems there were some manufacturing differences. Looks like I am going to have to do some filing and inleting to get the new tang to fit. The new tang is a bit thicker dimensionally. Should I file the tang to fit before inleting the stock? Any suggestions would be great.

Yes. File the tang first. You should be able to get pretty darn close on width, height, and filing the downward slope on the top of the tang. You've got plenty of metal there. Do a good job filing, and there won't be much inletting at all. Maybe none.

May be a dumb question but, why not just use the old tang?

There are two styles of tangs depending on the age. They are not intrchangable IIRC. Check the Duck Creek site to see the difference.

Appreciate the input. Got it all sorted. Filed the face of the old tang some and filed the bottom inside flat of the tang circled. Fits perfect. Now hopefully the drum will not interfere with the lock.

Ok barrel fits in the tang fine now. Used evaporust on the bore it's mirror bright now. So what is the best way to remove this exterior rust there is no pitting but will be if I don't neutralize what is there. Going to brown the Barrel.

I'd begin with coarse sand paper wrapped around a flat file, to get most of the crud off. Then I'd move to finer paper, or draw filing... depending on what it needs then.

I would steam the barrel to convert the rust or boil it, then card it.
